An insight to the offline and online data warehouses

In nontechnical language, the term data warehouse refers to a database that is used to keep account, study and access data within an organization or a company. Data within an organization is generally acquired from all departments – namely the sales, marketing, administration, warehouse, human resource and customer support department – of the organization or business enterprise. Sometimes the raw data that are acquired may go through some preprocessing before it is submitted to a data warehouse. In case of the traditional or the common old data warehouses – it sets up main tasks by way of separate arrangement, assimilation and admission. The arrangement or staging area collects and stores the raw un-processed data that is acquired from different sources across the organization. The assimilation or integrated area processes and transforms the collected data into a format that is suitable for reporting. The data is then made available for access to users within the organization.

In the beginning, data warehouses that were used by organizations were offline operated data warehouses – wherein the data had to be updated at periodic intervals on a weekly or monthly basis and was saved in a report like format. The next were the offline data warehouses –wherein the data were updated from operational systems on a regular basis and was stocked up in a format that supported the reporting process. After a while the offline data warehouses were outdated, and in came the new online data warehouses – wherein data updates in actual time by way of keeping record of every single transaction that is carried out from the starting point. With the latest evolution being the integrated date warehouse – which keeps data that is collected from across the different departments of the organization, thus enabling a user’s real – time access to intelligence information from across departments within the company.

Cleaning Of a Data Warehouse

A data warehouse stores innumerable amount of data that is pulled from various databases from across the world. The main use of a data warehouse is in strategic decision making. Like for example – it is with the help of a data warehouse that companies are able to offer promotional offers to all their valued customers. Without a data warehouse, it would become difficult for companies to realize how much profit or loss has been generated. Here we are not speaking about one company having an office in a commercial building, but we are speaking about giant companies such as Pepsi and Coke that have offices based across the globe.

That is the reason why we have mentioned that a data warehouse is very important when a company has many branches all over. With so much data being made available from all over, it is equally important to clean the data warehouse occasionally. Remember, there are no data cleaner which can be used for the entire data warehouse. Therefore the best method to clean a data warehouse is to conduct analysis, that is to understand the exact context of the entire data. Based on this analysis, we will have to create transformation rules to help transform all the unwanted data to clean data. All these transformation rules then have to be verified with the help of simple data so as to make very sure that the rules are working as intended.

Once the entire cleaning procedure has been completed, it is very important that human intervention is required to make sure that there are no more unwanted data still in the data warehouse. This cannot be eradicated or checked automatically, but human help is necessary. This is why we must plan to clean our data warehouse. Periodic cleaning is very important for data warehouse.

Reason for Having a Data Warehouse

There are many questions put forth such as to provide a reason to why a company requires a data warehouse and what are its benefits? Well in simple terms, in case you wish to get any information about your company such as finding out the turnover of your business for the current month or last month or even last year, find out the number of employees in your firm, the number of sales generated by each and every salesman in your company and which employee is topping the list etc. All these can be found out from a data warehouse.

The best part of a data warehouse is that if you have branches in different regions, you can link each of these branches and find out the sales from each of the branches in a particular day. A data warehouse is considered to be a resourceful and a well organized set of data which can be made available with the click of a button.

Another important feature is that this data cannot be used and checked by anyone. It can be checked only by an authorized person of the company such as the director of the company. To log in, they will have to enter a user name and a password and hence there is no fear that employees can sneak into the data to find out the information they require.

Data warehouse also helps in preparing various types of reports such as exception reports, trends reports, analyzing reports etc. Precisely, a data warehouse is very important for any company whether big or small. Having a data warehouse installed will help the company to push their sales to a different level altogether. They can also compare their sales before installing a data warehouse in their office and the achievement of sales after its installation. Definitely, the sales will show an upward trend with the help of a data warehouse.
